Resembling the shape of a horseshoe, horseshoe lifebuoys are made of buoyant material such as foam or plastic. They've been designed to be easily thrown to a person in distress in the water.
They offer a person immediate buoyancy and support in the water. Allowing you time in a man overboard situation to recover and rescue them.
Many horseshoe buoys come in bright colours for enhanced visibility. This helps to aid in locating and rescuing individuals in the water. Particularly in low light or rough weather and water conditions.
